Notes: Tzvelev, Elven, and Murray: All data on distribution are uncertain. The range given above and in the distribution table is based on the assumption that Deschampsia anadyrensis is the widespread plant to which the names D. glauca or D. cespitosa subsp. glauca have been applied in both Russia and North America (e.g., Tzvelev 1964g, 1976; Hultén 1968a; Hultén and Fries 1986), and the name D. cespitosa in much North American literature. We consider the use of the names "glauca" and "cespitosa" for these plants erroneous (see D. glauca under Excluded taxa). Another name is needed, and Tzvelev (1976) synonymized D. anadyrensis with his concept of D. cespitosa subsp. glauca. We are far from sure that D. anadyrensis is the correct or the priority name to apply. Neither do we have good evidence yet that the Russian and North American plants to which the name "glauca" has been applied are the same. Chiapella et al. in Soreng et al. (2003) synonymized the name D. anadyrensis with their concept of D. cespitosa subsp. cespitosa, i.e., including the native North American plants.
